Barcelona cruised to a 4-0 rout over 10-man Real Sociedad to regain the lead in Spain on Sunday, Marca reported.
Gerard Martín, Marc Casadó, Ronald Araujo and Robert Lewandowski scored a goal each to put Barcelona one point ahead of second-placed Atletico Madrid at the top of the Spanish league. Barcelona is three points ahead of third-placed Real Madrid, which lost 2-1 at Real Betis on Saturday, when Atletico beat Athletic Bilbao 1-0 at home.
Sociedad played a man down from the 17th minute after Aritz Elustondo was sent off with a straight red card for grabbing Barcelona forward Dani Olmo to stop a breakaway.
It was the sixth win in a row for Barcelona in the league, and the second loss in three matches for Sociedad, which stayed in ninth place.
